Create a Microsoft App

This skill scaffolds a new Microsoft App end-to-end using @microsoft/managed-apps-cli (binary ms). The default outcome is a running local dev server, not a deployed cloud app. Deploying is a separate, explicit user choice via /deploy.

Workflow

1. Memory Bank → 2. Prerequisites → 3. Infer App Spec → 4. Plan → 5. Auth → 6. Environment → 7. Scaffold → 8. Add Data Sources → 9. Add Backend (if requested) → 10. Implement App → 11. Local Dev → 12. Summary → 13. Memory Bank Update

Critical principle: when this skill ends and the user opens the local URL, they must see a functional app — connectors wired when required, screens implemented from the approved plan — not a bare template. Adding required data sources and implementing the UI happen inside this skill, before ms app dev is started. Do not defer them to "next steps."

Step 1: Check Memory Bank

Check for memory-bank.md per shared-instructions.md. If found, infer whether to resume or create a new app from the request: resume when it refers to the existing app or incomplete work; create a new sibling project when it clearly describes a different app. State the choice and continue. Ask only when the request genuinely fits both paths and choosing incorrectly could overwrite or modify existing work.

Step 2: Validate Prerequisites

Run prerequisite checks first — no point gathering requirements if the environment isn't ready. Full details in prerequisites-reference.md.

The commands below are shown in bash syntax. If you are running PowerShell on Windows, use the equivalents described in shared-instructions.md and the PowerShell example in prerequisites-reference.md instead of copying the bash snippets literally.
